l h / ratios. Fig. 4 indicates a reduction of the dissipated energy with rise of 4  . It can also be seen in Fig. 4 that the dissipated energy increases rapidly when l h / ratio grows.

These variations are visualized in Fig. 5 where the dissipated energy is plotted versus  at three values of 0  . One can see in Fig. 5 that the dissipated energy grows as result of increase of  and 0  . 4. Conclusions The energy dissipation in a non-linear viscoelastic functionally graded beam structural component loaded in skew bending is studied theoretically. It is detected that:  the rise of parameter 1  induces a gradual growth of the dissipated energy;  the influence which the parameter 3  has over the dissipated energy is similar to this of 1  ;
